Question

把0.1,0.2,0.3,0.4,0.5这五个数运用运算符号链接起来,使结果分别等于1、2、3、4、5、6、7、8、9、

Answer 1

0.2 /(0.4+0.1)+(0.3/0.5) = 1

( 0.4-0.3+ 0.5*0.2)/0.1 =2

0.4*0.3* 0.5/0.2/0.1 = 3

(0.4/ 0.2) + (0.5+0.1)/0.3 = 4

(0.4/0.1-0.3/0.2)/ 0.5=5

(0.4 +0.5)*(0.2/ 0.3)/0.1=6

0.3/0.1 + 0.4/( 0.5*0.2 )=7

(0.1 + 0.3+ 0.4 )/(0.5*0.2)=8

0.4/(0.3 -0.2)+ 0.5/0.1 = 9

0.1/ (0.4-0.3)/( 0.5*0.2)=10
